Vedclass · Answer

(D) Meiosis is a specialized type of cell division that reduces the chromosome number by half,resulting in the production of haploid daughter cells.It involves two sequential cycles of nuclear and cell division,known as Meiosis-$I$ and Meiosis-$II$.However,these two divisions are preceded by only a single cycle of $DNA$ replication during the $S$-phase of interphase.Therefore,the correct description is two sequential cycles of nuclear and cell division but only a single cycle of $DNA$ replication.

Column $I$	Column $II$
$(a)$ Prophase-$I$	$(p)$ Nucleolus and nuclear membrane reappear
$(b)$ Metaphase-$I$	$(q)$ Longest phase
$(c)$ Anaphase-$I$	$(r)$ Homologous chromosomes align at the equatorial plate
$(d)$ Telophase-$I$	$(s)$ Number of chromosomes reaching each pole is half of the original cell
